Looks like this made it into 12.10. In my case it IS a duplicate of #1042225 and hitting escape once for the textual and twice for the graphical FDE password prompt works for me. I've upgraded from 12.04 (and before this I've been following stable releases). Removing the VT handoff option off the kernel line at boot makes the graphical prompt appear without screen blanking / the display switching to power saving / standby mode.
